Design Of Unmanned Ship Motion Control System Based On DSP And GPRS

For the construction of Baiyangdian Wetland Ecosystem Location Research Station,research station in the past have limitations, including limited coverage and can not monitor environmental conditions of wetland ecosystems in accordance with the wishes of the people.Moreover, the conventional mobile monitoring platform using Zig Bee networking technology for the transmission of information also have significant limitations. An automatically navigate unmanned patrol boat of long-distance information transformation is urgently needed for professional data acquisition and communication transmission of temperature and quality of wetlands and environmental monitoring. As a supplementary of dynamic monitoring of fixed site, unmanned patrol boat provide a more reliable basis for Baiyangdian wetland ecosystems scheduling and operation management. the present problem. In this paper,unmanned patrol boat motion control systems was designed on the basis of DSP and GPRS.In this design, we chosed high integration and high reliability TMS320F2812 DSP chip as the core processor. Unmanned patrol boat combined semi-automatic navigation control technology, Bei Dou Navigation Satellite System, ultrasonic intelligent obstacle avoidance technology and GPRS network wireless communications technology, and have many features,including carrying energy, navigating semi-automatically, achieving information transmission in wetland waters. In terms of hardware: Unmanned patrol boat can achieve interactive communication with the TMS320F2812 DSP host computer via GPRS wireless network; the circuit include UM220-III N BeiDou Navigation module, electronic compass module of HMC5883 L and ultrasonic sensor. In terms of software: writing programs for all hardware devices to achieve their respective functions, using the algorithm to realize automatic avoid-obstacle function by ultrasonic, adjusting the direction of travel by calculating the relationship of unmanned patrol boat's position and the final position for. The boat realized the control of semi-autonomous navigation.This technology can make up for vulnerabilities of monitoring and achieve semi-autonomous navigation in different waters of Baiyangdian. As a supplementary ofdynamic monitoring of fixed site, this technology is labor-saving and economical, people can monitor the Baiyangdian wetland water environment as they wish by GPRS wireless network to provide information resources for the Baiyangdian wetland ecosystem database.
